I think this core is extensively tested.
I have it running on a Spartan II FPGA (XC2S100) communicating to a
Microchip 24LC02B EEPROM. The memory have 3.3 V of Vdd and is limiting
the communication clock to 367.25 KHz (datasheet says it can reach 400
KHz @ 5 V).
Did you simulate it? You can use the provided testbench, I did it to
test my system before trying the FPGA (my system have a 16C84 core and a
VGA character generator).
I used the core with some small changes, but they doesn't affect the I2C
side (just the wishbone side).
